Copic : Multiliner : Pigment Pen : Cool Grey : Set of 4

�The copic multiliner pens were specially developed for graphic artists, industrial designers, and architects who need a pen that can stand the test of time. When over-drawing with COPIC or COPIC sketch Markers, the tracing line remains sharp and does not bleed. These pens contain a waterproof, acid-free archival quality-based pigment that can hold its ink whilst being resistant to UV light.�This set includes cool grey coloured fineliners in the sizes: 0.03, 0.05, 0.1 and 0.3.�
